^^^this is how I solved this problem with mine... insulating the lines helped to a degree but didn't completely solve it until installing bypass regulator with return to the tank... the cause in my car was poor air circulation in the engine compartment likely due to the absence of inner fender wells but this often happens when fuel line close to exhaust as you described... start with sleeving the line in that area (I use the orange sleeve heat shield material, I don't know what it's called). If you continue to have problems, a bypass regulator will fix it for good.
